What is Varioliform Gastritis?

Varioliform gastritis is a chronic inflammatory condition of the stomach characterized by the presence of multiple small, crater-like ulcers resembling pockmarks or varioliform lesions (hence the name “varioliform”). These lesions primarily affect the mucosal lining of the stomach, causing a distinct pattern of inflammation and erosion.

Unlike more common types of gastritis, such as Helicobacter pylori-associated gastritis or autoimmune gastritis, varioliform-gastritis has a unique morphological presentation and different underlying pathology. It can cause persistent discomfort and may be linked to other systemic autoimmune or dermatological conditions.

Symptoms of Varioliform Gastritis

The symptoms of varioliform gastritis can vary depending on the severity and extent of the gastric mucosal involvement. Many patients initially present with non-specific gastric symptoms that overlap with other types of gastritis or peptic ulcer disease. Common symptoms include:

1. Upper Abdominal Pain or Discomfort

Often described as a burning or gnawing sensation, this pain is usually located in the upper abdomen (epigastric region). The pain may worsen after meals or on an empty stomach.

2. Nausea and Vomiting

Some patients experience frequent nausea and occasional vomiting, which may contain blood if ulcerations become severe.

3. Loss of Appetite and Weight Loss

Chronic inflammation and discomfort can reduce appetite, leading to unintentional weight loss.

4. Bloating and Fullness

Patients may feel bloated or experience early satiety after eating small amounts of food.

5. Gastrointestinal Bleeding

In more advanced cases, the varioliform lesions can bleed, causing melena (black tarry stools) or hematemesis (vomiting blood).

6. Fatigue and Weakness

Chronic blood loss from gastric ulcers can lead to anemia, resulting in fatigue, weakness, and pallor.

7. Other Possible Symptoms

Some patients report heartburn, belching, or a sour taste in the mouth.

Causes and Risk Factors of Varioliform Gastritis

The exact cause of varioliform gastritis remains not fully understood, but it is believed to involve a combination of factors leading to chronic mucosal damage and inflammation.

1. Autoimmune Mechanisms

One prominent theory is that varioliform-gastritis has an autoimmune basis. The body’s immune system may mistakenly attack gastric mucosal cells, leading to chronic inflammation and ulcer formation. It often coexists with other autoimmune disorders such as thyroiditis, vitiligo, or pernicious anemia.

2. Infections

While Helicobacter pylori infection is a common cause of chronic gastritis in general, its role in varioliform-gastritis is less clear. Some cases show no evidence of H. pylori, suggesting other infectious or non-infectious triggers.

3. Genetic Predisposition

Genetic factors may increase susceptibility, especially in individuals with family histories of autoimmune or gastrointestinal diseases.

4. Chronic Use of NSAIDs or Alcohol

Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) or excessive alcohol consumption can irritate the gastric lining, potentially worsening or triggering gastritis.

5. Other Environmental and Lifestyle Factors

Smoking, stress, and dietary habits may contribute to the development and progression of gastritis.

Types of Varioliform Gastritis

Though varioliform gastritis itself is a specific form, it can present with some variation depending on the pattern of lesions and the underlying pathology:

1. Idiopathic Varioliform Gastritis

This type occurs without an identifiable cause and is purely characterized by its unique morphological features — multiple small ulcers with raised borders resembling variola or smallpox scars.

2. Autoimmune Varioliform Gastritis

Associated with autoimmune diseases, this type involves immune-mediated destruction of the gastric mucosa and may overlap with autoimmune gastritis affecting the gastric fundus and body.

3. Secondary Varioliform Gastritis

Secondary to other underlying causes such as infections (rare), drug-induced injury, or systemic diseases that affect the gastric mucosa.

How is Varioliform Gastritis Diagnosed?

Because varioliform gastritis is rare and symptoms mimic other gastric conditions, diagnosis requires a thorough clinical and investigative approach.

1. Clinical History and Physical Examination

A detailed history of symptoms, medication use, family history of autoimmune diseases, and lifestyle factors are essential.

2. Upper Gastrointestinal Endoscopy

Endoscopy is the gold standard diagnostic tool. The procedure allows direct visualization of the gastric mucosa. Varioliform gastritis appears as multiple small crater-like ulcers or depressions scattered across the stomach lining, often with surrounding inflamed and erythematous mucosa.

3. Biopsy and Histopathology

During endoscopy, biopsy samples are taken from the lesion areas. Histological examination shows:

• Chronic inflammatory infiltrate dominated by lymphocytes and plasma cells.
• Focal erosions or ulcerations with regenerative changes.
• Possible glandular atrophy in autoimmune-associated cases.
• Absence or presence of H. pylori depending on the case.

Histopathology confirms the diagnosis and helps rule out malignancy or other gastric diseases.

4. Laboratory Tests

Blood tests may show anemia or autoimmune markers if related conditions are suspected. Testing for H. pylori infection is also routine.

5. Other Imaging or Tests

Rarely, imaging such as abdominal ultrasound or CT scans may be done to evaluate complications or rule out other causes.

Treatment of Varioliform Gastritis

There is no standardized treatment specifically for varioliform gastritis due to its rarity, but management focuses on:

1. Eradication of Helicobacter pylori (If Present)

If H. pylori infection is detected, triple or quadruple therapy with antibiotics and proton pump inhibitors (PPIs) is initiated.

2. Acid Suppression Therapy

Proton pump inhibitors or H2 receptor antagonists are prescribed to reduce gastric acid secretion, promote mucosal healing, and relieve symptoms.

3. Immunosuppressive Therapy

For autoimmune-related varioliform gastritis, corticosteroids or other immunosuppressants may be considered under specialist care to control immune-mediated inflammation.

4. Avoidance of Irritants

Patients are advised to avoid NSAIDs, alcohol, smoking, and any foods or substances that exacerbate gastric irritation.

5. Nutritional Support

In cases of malnutrition or weight loss, dietary modifications and supplementation with vitamins and minerals may be necessary.

6. Treatment of Complications

If bleeding ulcers or anemia develop, endoscopic interventions, blood transfusions, or iron therapy might be required.

7. Regular Monitoring

Follow-up endoscopy may be needed to monitor healing and detect any progression or complications such as precancerous changes.

Prognosis and Complications

Varioliform gastritis tends to be chronic and relapsing but can be managed effectively with appropriate treatment. Potential complications include:

• Chronic bleeding leading to anemia.
• Gastric outlet obstruction if scarring is extensive.
• Increased risk of gastric malignancy in long-standing cases, especially those linked to autoimmune gastritis.
• Persistent symptoms affecting quality of life.

Early diagnosis and proper management significantly improve outcomes.

Preventive Measures

Though varioliform gastritis cannot always be prevented, certain measures reduce risk and aid early detection:

• Prompt treatment of Helicobacter pylori infections.
• Avoiding chronic use of NSAIDs and alcohol.
• Managing autoimmune disorders with regular medical follow-up.
• Adopting a healthy lifestyle with balanced nutrition and stress management.
• Seeking medical advice for persistent gastric symptoms.

Conclusion

Varioliform gastritis is a rare but clinically significant form of chronic gastritis with unique ulcerative lesions. Recognizing its symptoms, understanding its possible autoimmune or infectious origins, and utilizing proper diagnostic methods like endoscopy and biopsy are crucial for effective management. While treatment primarily involves acid suppression and addressing underlying causes, immunosuppressive therapy may be necessary for autoimmune cases.
